Eh wanton Patented Oct. 22, 1929 UNITED S 145 ATES JAMES O. NASH, F DUKE, OKLAHOMA PUMP Application. filed August 5,

This invention relates to pumps of the type disclosed in Letters Patent, No. 1,639,956, granted to me August 23, 1927, the object of the present improvements being to increase the capacity of the apparatus and to provide means whereby the pump may be manually operated without exposing the operator to possible injury through contact with the power driving elements. Another object of the invention is to provide means for avoiding wear and binding around the fulcrums of the operating lever and also to provide a very simple and inexpensive means whereby delivery of the liquid raised by the pump at a high ele- 1 vation will be facilitated. The invention is illustrated in the accompanying drawing and will be hereinafter fully set forth.

In the drawing:

Figure 1 is an elevationof an apparatus embodying the present invention;

Fig. 2 is an enlarged detail section on the line 50-50 of Fig. 1, and

Fig. 3 is an enlarged sectional elevation of the structure whereby wear upon the pivots Z5 is avoided.

In carrying out the present invention, I employ a substantial supporting frame consisting of posts 100 connected rigidly by braces 101 having tenoned connections with the respective posts and provided in any desired number. If desired, diagonal braces may be provided between the braces 101. The posts and braces are so arranged as to pro: vide guides for pump rods and the supporting frame is erected around the mouth of a well so that the pump rods will be arranged to operate within barrel or pump casings de pending into the well. In the drawing, I have shown four barrels 102, 103, .104: and 105, and it will be noted that these pump barrels rise to difilerent heights within the frame. At the upper end of each pump barrel, there is fitted thereto a sleeve 106 which is internally threaded and Within the sleeve there are provided disks 107 which have threaded connections with the sleeve. The opposed faces of these disks are preferably concave, as shown at 108, and between the disks packing 109 of any preferred or approved type is provided, the disks being provided with central 1927. Serial No. 210,890.

openings through which the pump rod 110 passes and the packing fitting about the pump rod and being compressed around the same by adjusting the disks in an obvious manner. Each disk is provided with an angular hub or collar 111 on its plane face so that it may be easily engaged by a turning tool, and it will be understood that rotation of either disk will cause it to move longitudinally of the coupling sleeve and thereby compress the packing. This structure is exceedingly cheap and may be applied to any pump barrel. The discharge spout 112 of the pump leads laterally from the pump barrel at a point below the upper end of the same and communicates directly with a pipe 113 which may be carried to any point of delivery and it will be understood that the spout may be of any approved form and secured or coupled to the barrel in any convenient manner. Many umps leave the upper ends of the barrels entirely open and the water will be lifted to the discharge spout 112 but if the delivery pipe 113 extends to a level above the horizontal plane of the discharge spout, the water will simply overflow through the upper end of the arrel. By providing the packing sleeve and the compressing disks shown in detail in Fig. 2, I close the upper end of the pump barrel and any air which may be in the barrel above the level of the discharge spout will be compressed by the rising of the water in the barrel and will exert a pressure upon the water or other liquid which will coact with the force exerted by the pump rod and the plunger or piston so that the water may be delivered wherever desired.

The innermost pump barrel 102 rises to a point near the top of the supporting frame and the pump rod 110 thereof is formed with or rigidly secured to a driving bar 114 which may extend up to a windmill so that the pumps may be operated by the power generated by the wind wheel. Pivoted to the sides of the driving bar 114 are pendent links 115 which have their lower ends pivotally engaged with metal straps 116 secured to the sides of a wooden bar 117 and projecting beyond the ends of said. bar in order to accommodate the links and be pivotally connected therewith. The wooden bar or body 117 and The lever is fulcrumed between adjacent posts 100 upon a pin 118 which passes through the postsadj acent theinner edge thereof. In

' wet weather, the wooden bar 117 absorbs moisture and swells so that it tends to bind about the pivot pin and thereby cause the pump to operate with difficulty, besides causing excessive wear upon the contacting surfaces. To

overcome this difficulty, I provide a bushing 119 which extends through the lever and fits around the pivot pin or bolt so that the swelling of the, wooden body will not cause bind.- ing upon the pivot. To prevent rotation of the bushing relative to the wooden lever body, a keyway is formed through the body and the bushing is provided with a longitudinal radial rib 120 seating in the keyway, as shown in Fig. 3., I alsoprovide-an oil cup 121 which is: carried by the lever and has its outlet extending through the lever todeliver lubricant through an openingprovided therefor in the bushing to reach the opposed surfaces of the bushing and the pivot. The bushings and oil cups will be generally provided also at the ivotal connections between the levers and the links to bepresently mentioned.

The driving red 11 1 is guided by rollers, indicated at 122, and a similar drivingrod isprovided in alinement with each pump barrel, the several driving rods being designated 123, 12 i and 125. Toeach of theselower driving rods are pivoted links 126 corresponding in all respects to the links 115,

and levers 127, 128 and 129 are pivotally connected to the respective links so as to actuate the several driving rods 123, 121 i and 12.5.

These levers are pivotally mounted in the frame in the same manner as the upper lever, which has been described, is mounted, and it. will be noted that the respective piv- 1 ots1'30, 131 and 132 are disposed in different vertical planesso that a line passing through all the pivots will be parallel with a line passing through the topsof theseveral pumpbarrels, the leverage exerted: upon each driving rod and connected pump rod,.censequent- Ly, being the same. A diagonally disposed connecting rod or link 133 is pivoted at its upper. end to the outer end of the topmost lever and at its lower end to the inner end: of the lever 127 coincident with the pivotal attachment of the links 126 thereto. A similar inclined link or connecting bar 134; is likewise connected; to the levers 128 and 129 and the; levers 12'. and 128 are connected by a link 135 which is pivoted to and extends between the outer ends of the same. The le- 9 vers 127 and 128 will, consequently, always opposition to the lever 128, the movements of the several pump rods being thereby balanced. Interference between the several pump rods and the levers will not occur inasmuch as the metallic straps secured to the sides of the wooden bodies pass beyond the ends of the levers and when any pump rod moves toward a superposed or a subjacent lever, the end of the rod will pass through the space between the ends of the metallic straps and beyond the end. of the wood lever body. This feature is advantageous where, for any reason, the vertical distance between levers must be restricted. The lowermost lever 129 is provided with an opening 136 therethrough at its outer end so that it may be pivotally connected with a pump jack driven by a steam engine or other convenient motor, or may have a handle connected thereto. If preferred, a pump jack may be connected to one of the upper levers. This arrangcment provides for an e'l'ficient operation of a plurality of pumps within a single well and will be particularly advantageous in irrigation projects inasmuch as the well may be made of large diameter to accommodate a large number of pumps and the water raised by the several pumps may be delivered at different points so that the benefits thereof may be spread over a considerable territory.

Thedischarge from two or more pumps may be delivered at one point and many forms or arrangements of pipe connections may be employed between the outlets.

In some localities, it may be inconvenient to obtain mechanical or electrical power for operating the pumps and manual labor may applied. This coupling bar 137 depends to a point near the ground and is pivoted to a lever 138 corresponding in construction to the levers 127, 128 and 129 and projecting outwardly from the side of the supporting frame upon which it is pivoted. To the outer end of this lever 138 is secured a ham dle 139 which may be manually grasped and operated, and it will be understood that a cross bar of any desired length may be fixed to the handle so that a'large number of laborers may be enabled to grip the same and operate the apparatus. If necessary, a handle and cross bar may be attached to the lever 129, and it will be understood that the frame and series of pumps may be duplicated to any extent permitted by any given circumstances.

Having thus described the invention, I claim:

In a. pumping apparatus of the type detill scribed, a plurality of levers, a link pivoted to and connecting the outer ends of intermediate levers, a, link pivoted to and connecting the inner end of the lowermost lever With the outer end of the next lever above, a link pivoted to the outer end of the uppermost lever and to the innermost end of the next subjacent lever, and means for applying power to one of the levers.

In testimony whereof I aflix my signature.
